For an eagle's-eye view of the waterfall and spring below, turn off Route 40 at the orange sign for Ein Avdat to get to the Ein Avdat Observation Point. Below you is the white canyon carved out by the Zin River, with its waterfall (most of the year) tumbling into a pool surrounded by greenery. From the lookout, a path leads around the top of the cliff (be very careful), enabling you to see the rope marks in the rock; these have been created over the years by Bedouin pulling
up water buckets. For information on the hike from here to ancient Avdat, consult the Field School at Sde Boker College.
